O método dos parâmetros fundamentais em FRX e sua implementação efetiva
As tecnicas de caracterizacao de materiais, em especial a difratometria de raios X (DRX) e a espectroscopia de fluorescencia de raios X (FRX) tem se desenvolvido a passos largos desde a descoberta dos raios X no final do seculo XIX e da observacao do fenomeno de difracao dos raios X por cristais no inicio do seculo XX…
Emergence of Cooperativity in Plasticity of Soft Glassy Materials
The elastic coupling between plastic events is generally invoked to interpret plastic properties and the failure of amorphous soft glassy materials. We report an experiment where the emergence of a selforganized plastic flow is observed well before the failure. For this we impose an homogeneous stress on a granular ma…
STUDY OF THE THERMAL STRATIFICATION IN PWR REACTORS AND THE PTS (PRESSURIZED THERMAL SHOCK) PHENOMENON
In the event of hypothetical accident scenarios in PWR, emergency strategies have to be mapped out, in order to guarantee the reliable removal of decay heat from the reactor core, also in case of component breakdown. One essential passive heat removal mechanism is the reflux condensation cooling mode. This mode can ap…
Superconducting proximity effect in inverted InAs/GaSb quantum well structures with Ta electrodes
We present our recent electronic transport results in top-gated InAs/GaSb quantum well hybrid structures with superconducting Ta electrodes. We show that the transport across the InAs-Ta junction depends largely on the interfacial transparency, exhibiting distinct zero-bias behavior. For a relatively resistive interfa…
The Shirley reduced basis: a reduced order model for plane-wave DFT
The Shirley reduced basis (SRB) represents the periodic parts of Bloch functions as linear combi- nations of eigenvectors taken from a coarse sample of the Brillouin zone, orthogonalized and reduced through proper orthogonal decomposition. We describe a novel transformation of the self-consistent density functional th…

Annealing-induced enhancement of ferromagnetism and nano-particle formation in ferromagnetic-semiconductor GeFe
We report the annealing-induced enhancement of ferromagnetism and nano-particle formation in group-IV-based ferromagnetic-semiconductor GeFe. We successfully increase the Curie temperature of the Ge0.895Fe0.105 film up to ~220 K while keeping a single ferromagnetic phase when the annealing temperature is lower than 50…
Lighting up topological insulators: large surface photocurrents from magnetic superlattices
The gapless surface states of topological insulators (TI) can potentially be used to detect and harvest low-frequency infrared light. Nonetheless, it was shown that significant surface photocurrents due to light with frequency below the bulk gap are rather hard to produce. Here we demonstrate that a periodic magnetic…
Emergence of cooperativity in plasticity of soft glassy materials
The elastic coupling between plastic events is generally invoked to interpret plastic properties and failure of amorphous soft glassy materials. We report an experiment where the emergence of a self-organized plastic flow is observed well before the failure. For this we impose an homogeneous stress on a granular mater…

Phase Retrieval with Application to Optical Imaging
This review article provides a contemporary overview of phase retrieval in optical imaging, linking the relevant optical physics to the information processing methods and algorithms. Its purpose is to describe the current state of the art in this area, identify challenges, and suggest vision and areas where signal pro…
Measuring Strain Variation of Pretreated Wood during Drying Using an Optical Measurement System
Surfacing, steaming and freezing are widely used pretreatment methods to improve the drying rate and to reduce drying defects of wood. In this study, Douglas fir (Pseudotsuga menziesii) wood samples were treated with steaming or freezing, and the resulting drying behaviors such as drying rate, drying strain and drying…
Formulation and Evaluation of Mefloquine Hydrochloride Nanoparticles
The present study deals with the formulation and evaluation of mefloquine hydrochloride nanoparticles. Mefloquine is a blood schizonticidal quinoline compound, which is indicated for the treatment of mild-to-moderate acute malarial infections caused by mefloquine-susceptible multi-resistant strains of P. falciparum an…
Band Gap Engineered P3HT/CdPbS Composites for Utilization of Low Energy Photons
In the present study, CdPbS composite has been synthesized in the P3HT matrix in a single step. The synthesis has been carried out at a temperature of 120 degrees C by the decomposition of xanthate compound in the polymer matrix. This synthesis method helps in proper distribution of nanoparticles in the polymer matrix…
Substituent Effect on the Self-Assembled Structures of Two Carboxyl-Functionalised Phthalocyanine Derivatives on Highly Oriented Pyrolytic Graphite
The self-assembling behaviour of two kinds of 4-carboxyphenoxy phthalocyanines (Pc1 and Pc2) has been investigated by scanning tunneling microscope (STM). Pc1 and Pc2 are isomers with the same substituent at alpha- andbeta-position of the phthalocyanine core, respectively. Our STM results have shown that the Pc1 molec…
